Summary: Enables protein kinase activity. Involved in several processes, including negative regulation of macromolecule biosynthetic process; negative regulation of sterol import; and sterol import. Located in nucleus and plasma membrane. Human ortholog(s) of this gene implicated in breast cancer; ductal carcinoma in situ; non-syndromic X-linked intellectual disability 30; renal cell carcinoma (multiple); and schizophrenia. Orthologous to several human genes including BUB1B-PAK6 (BUB1B-PAK6 readthrough); PAK1 (p21 (RAC1) activated kinase 1); and PAK2 (p21 (RAC1) activated kinase 2).

What's a GeneRIF?

Results suggest that the Cdc42 effectors Ste20, Cla4, and Skm1 translocate into the nucleus, where they modulate expression of sterol uptake genes via Sut1, thereby controlling sterol homeostasis.
Title: The Cdc42 effectors Ste20, Cla4, and Skm1 down-regulate the expression of genes involved in sterol uptake by a mitogen-activated protein kinase-independent pathway.

Preferred Names: putative serine/threonine protein kinase SKM1

NP_014528.1

EC 2.7.11.1

Member of the PAK family of serine/threonine protein kinases; similar to Ste20p; involved in down-regulation of sterol uptake; proposed to be a downstream effector of Cdc42p during polarized growth; SKM1 has a paralog, CLA4, that arose from the whole genome duplication
